University of California: Martha Heil: Plexiglas makes nanowire batteries last longer

In the race to make more efficient batteries, scientists would like to pack together tiny nanowires that could be charged many times over. A team from University of California, Irvine, has coated these nanowires with plexiglas-like-gel, and found that they last much longer than other or uncoated nanowire batteries. Researcher Mya Le Thai explains.
